Temporal control of light echoes

Scientists at Paderborn University, the Technical University of Dortmund and the University of W├╝rzburg have for the first time used laser pulses to precisely control photon echoes, which can occur when light waves superimpose ...

Transmitting data from space to earth with laser filaments

Could light be used to transmit information between satellites and Earth? Atmospheric water vapor scatters and absorbs light energy, but overcome that obstacle, and light will carry far more information and move it faster ...

Researchers develop nonlinearity-induced topological insulator

Researchers from the University of Rostock have developed a novel type of nonlinear photonic circuitry in which intense light beams can define their own path and, in doing so, render themselves impervious to external perturbations. ...

Single laser produces high-power dual comb femtosecond pulses

Researchers have developed a new approach that uses a single laser cavity to create two high-power optical frequency combs emitting high-power femtosecond pulses. The new development paves the way for portable dual-comb light ...

May the force be with you: Detecting ultrafast light by its force

A McGill research team has developed a new technique to detect nano-sized imperfections in materials. They believe this discovery will lead to improvements in the optical detectors used in a wide range of technologies, from ...

Light sensors detect larval pests munching on date palms

A red beetle, classed as the most destructive date palm pest, causes millions of dollars of annual economic losses worldwide. Now, a small team in Saudi Arabia has found a cost-effective approach that uses laser pulses to ...
